One thing that is easily overlooked and often skimped on is a solid PSU. No its not flashing and it won’t bump you benchmark shores up. However, it’s a real shame to whatch a multi-grand rig go up in literal smoke beacuase of a cheap PSU.

Be weary of kits. They are usually bundled with sub-par parts and result in more problems then they are worth. I made this mistake with my first pi purchase and did not get the pictured sd card or wifi adapter. Resulting in the SD card failing and wifi connection being spotty.
